for Tuesday, November 27.
Version A:
Two solid, metal spheres are connected by a thin copper wire and
separated
by 5 m. A total charge of
+5 pC is placed on the two sphere
I wire system. If
the radius of the larger sphere
is 20 cm and the radius of the smaller sphere
is 5 cm, (a)
what is the electric potential at the surfaceof the smaller sphere,
(b) what is the electric
potential at the center of the smaller sphere?
Version B:
Two solid, metal spheres are connected by a thin copper wire and
separated by 5 m. A total charge of
+5 pC is placed on the two sphere
/ wire system. If
the radius of the larger sphere
is 20 cm and the radius of the smaller sphere
is 5 cm, (a)
what is the electric field strenglh
just
above the surface of the smaller sphere,
(b) what is
the electric field strength at the center of the smaller sphere?
Version C:
Two solid, metal spheres are connected by a thin copper wire and
separated by 5 m. A total charge of
+5 pC is placed on the two sphere
/ wire system. If
the radius of the larger sphere
is 20 cm and the radius ofthe smaller sphere
is 5 cm, (a)
